The Android 4.4.3 Dialer app features a series of cards for each contact instead of a list. The cards have a colored background with the first initial of the name placed on them, but they can apparently also show a picture of the contact when one is assigned to it. Other elements in the screenshot include the top search bar and the bottom blue action bar.

The new Dialer app was apparently spotted on a Nexus 5 handset running Android 4.4.3 firmware version KTU84F. Android Police speculates that the Nexus 5 belongs to a Googler, considering the names of some of the contacts.
